MACHINE FOR MANUFACTURING CRIMPED PAPER CUPS.

Application filed April 16, 1921. Serial No. 461,855.

To all whom it may concern:

Be it known that I, EDWIN L. ELWELL, a citizen of the United States ofAmerica, residing inthe city of Baltimore, State of Maryland, haveinvented certain new and useful Improvements in Machines forMannfacturing Crimped Paper Cups, of which the following is aspecification.

This invention relates to a machine for producing paper wrappers or cupsused in packing or wrappingor as a receptacle for individual candies orpieces of candy, as chocolates, bon-bons and the like; the wrappers orreceptacles being usually and preferably in the form of paper discshaving a flat circular central portion constituting the bottom of thecup and having a wide margin or edge portion which is crimped or leatedto form the wallsor sides of the cup. everal machines for thispurposeare known to the patented art, the present invention beingunderstood to relate to certain improvements or to an improved type ofmachine.

The machine as shown which is an embodiment of the preferred form of'theinvention consists of a dial or carrier plate having a step by steprotation and a .plurality of dies with which openings or pockets in thedial register at each dwell in combination with two separatereciprocating heads carrying a cutter and a bumper and punchrespectively and timed and placed as hereinafter described, to cooperatewith the dial and dies together with means for feeding a web; ofmaterial as paper, whereby blanks are cut'from the web of paper by meansof the reciprocating cutter acting in cooperationwith one of said diesknown as the cutting die and carried by the dial to the otherreciprocating head, which crimps the blanks thus cut acting inconnection and in combination with the other die, theparts I being soarranged and placed that the dial in its step by step rotation bringseach set of blanks cut by the cutter, into cooperative relation with thecrimping die to be acted upon as aforesaid. I

An important feature of the machine resides in the crimping means whichincludes a bumper which strikes the blanks forcing them into theserrations of the crimping diewhere they are held not by positive but bya spring tension provided by means of springs which take up an excessivebacklash or play in the bumper mech anism' provided for that purpose,the operabetween the bumper and the die, overcom-v ing the springtension which tends to hold the bumper against the die and perfectingand completing the crimping action as more fully hereinafter explained.

' Other features of the machine relate to the step by step motion of thedial which is preferably driven in connection With the bumper and punchand may be positioned by the. bumper and punch mechanism or meanscarried thereby or causing the dial to stop with a pocket or openingcarrying the paper blanks in registration with the die and in the pathof the punch and bumper.

In order to provide for the cooperation of -the cutter with the dial,means are provided for stopping the cutter or the reciprocating head bywhich it is carried whenever the dial with its carrier openings orpockets move out of registration or out of alignment with the cutter.This in the present instance is, accomplished by withdrawing a key whichconnects the reciprocating mechanism carryingthe cutter to its driveshaft.

In the form of the machine shown, the cutter and die are driven byseparate belts, the dial as aforesaid being timed to cooperate with bothsaid mechanisms.

In the accompanying drawing I have illustrated a cutting and punchingmachine for producing paper cups or wrappers emplan indicated Fig. 4 isa detail view of the timing mechanism operating in connection with thereciprocating head which carries the cutter, the dialserving to maintainthe proper timin relation between the cutter and dial.

Fig. 5' is a detail of the clutch mechanism embodied in the timingapparatus.

Fig. 6 is a section on the line 6'6 of Figure 5.

Fig. 7 is a vertical central section through multiple.

shown in section.

,Fig. 9 is a horizontal section on the line 9-9 of 'Fig. 2.

Figs. 10 and 11 are views of the cup or wrapper made by the machine.

Referring to the drawings by numerals, each of which is used to indicatethe same or similar parts in the different figures, the machine as showncomprises two reciprocating heads indicated in a general way by reference characters 1 and 2 respectively, an in termittent'ly rotatingdial 3 andsuitable cutting and forming dies.

The reciprocating head 1 being the cutting head and the reciprocatinghead 2, the die pressing or bumping and punching head. In the form ofthe invention shown, the cutting and die pressing heads are separatelydriven. The reciprocating head 1 being driven by means of a Suitablebelt 5, which engages a pulley 6 on a shaft 7, which sha ft at the end 8is provided with an offset or crank 9 carrying a crank pin 10 which actuates a connecting rod 11, connected at its lower end by a suitable wristpin and bearing 12, to a sliding cross head 13 which .reeiprocates insuitable stationary upright guides 14. It-will be noted that as shown.

the throw of the crank 9 is adjustable by means of an eccentric 15enclosing and surrounding the crank pin' 10 within the connecting rodbearing 16 atthe upper end of y the connecting rod. The manner ofadjustment is by loosening the bearing 16 and rotating the eccentric.The cross head 13 carries a cutter 17 which cooperates with a circulardie l8,cutting circular blanks, or blanks of the desired shape according.to the form of the cutting die from a web or webs 19, fed over the dieand beneath the cover plate 20 as hereinafter described. The webs areordinarily fed in Referring now to the opposite end of the machine,particularly to the die pressing and punching head 2, the die pressingand punching mechanism is driven by means of an ordinary belt and pulley220 and 21, the

belt being in the illustration Fig. 1, shown as in engagement with theloose pulley 22 to which the belt may be shifted when the machine isidle. The pulley 21 is secured to drive shaft 23 which has a suitablebearing in the frame of the machine at 24,- and carries-a toothed gear25 rigidly secured to the pulley and meshing with a toothed gear 26 on ashaft 27 The cutter has, suitably spaced bearings 28, 29 in the frame ofthemachine.-At the opposite end of the shaft 27 from the toothed gear 26and mounted on and rigidly secured to said shaft 27-, is an eccentric31, see Fig. 7 encircled by an eccentric strap 32 carrying an eccentricrod 33 connected by means of a wrist pin 34 to a reciprocating crosshead 35, which travels in a vertical path in suitable upright guides 36.

An important feature of the invention relates to the provision of aconsiderable clearance 87 between the strap 32 andthe eccentric, theeccentric strap being given a downward tendency by means of spiralsprings 38 attached at their upper ends 39 to the strap and at theirlower ends to stationary points on the machine at 40, the springs beingnormally under tension. This permits the mechanism to strike or to bumpit on the die imparting an initial crimp, the positive pressure beingremoved as the eccentricrotates past its lower dead point and aresilient spring pressure being maintained which permits the paper to bedrawn through the die by the punch, overcoming the spring pressure andproducing a most satisfactory final crimping action as hereinafterdescribed.

The bumping or upper bumping die carried by the-reciprocating cross head35 is illustrated in Figure 7 in section and in Figure 2 in elevation,and indicated by reference character 41; it has a central aperindicatedby reference character 45 are serrated in corresponding radial ridgesand grooves to produce corresponding crim s or pleats in the paper. Theposition 0 the upper or bumping die 11 relatively to the eccentric rod33 is adjustable by means of an eccentric 46 enclosing and encirclingthe wrist 'pin 34 within the eye 48 of the wrist pin bearings at theupper end of the cross head 35; the manner of adjustment by retation ofthe eccentric will be understood.

To actuate the punch 43 the eccentrie31 is provided with a crank pin :47projecting from its outer face. The crank pin operates a connecting rod50, the wrist pin 51 and sliding cross head '52, which likewise travelsin guides 36. The punch 43 before mentioned, is mounted at its upper endin the lower end of the cross head 52 havingin.

,fact a. shank 53 seated inan aperture in the crank pin 47 as shown isset from 45 to 60 back of the point of maximum throw or greatest radiusof the eccentric as indicated by referenoecharacter 56 in Fig. 2; the

-- pressing die to strike its blow at the bottom dead point of the eccentric acting with a positive pressure when all the back lash or play istaken up and then, i. e., after the eccentric 31 passes the dead point,the bump er or upper bumping die 41, is held in contact with the paperby the action of the springs. After the positive pressure of the bumperhas been releasedby rotation of the eccentric and while the paper isheld. between the upper or bumping. die 41 and the lower or stationarypressing die 44 by the tension of springs 38, the punch 43 comes incontact with the center of the paper blanks tending to pusli themdownward through the apertures in the lower stationary pressing die 44,-the same being indicated by ref erence character 49. Thls causes theedge portions of the blanks to be drawn with a considerable degree oftension through the cooperating serrated surfaces 45, completing andperfecting the pleats or crimps in the paper as aforesaid.

Having further reference to the die pressing and punching head 2, theshaft 27 carries a sprocket (see Fig. 1) which drives a chain 62 whichin turn meshes with a sprocket 63 secured to a shaft 64 mounted insuitably spaced bearings 66 and carrying a web feeding roller 67.Cooperating with the roller 67 is an upper feed roller 68 on a shaft .69mounted in bearings 70 suitably spaced as aforesaid, it being understoodthat the bearings 70 and 66are mounted in vertical ways or slots 71 insuitable standards or uprights .72, the bearings being semi-circular,the lower bearings 66 being turned up and the upper bearings 70 turneddownward, also set screws 73 are threadedinto the-ends of the uprights72 bearing at their lower ends against the semi-circular bearings'7Owhereby suitable tension or pressure is applied to the rollersregulating the contact pressure and providing suitable ad- 'justment tothe thickness of Web or multiple web passed through the rollers. Theupper roller 68 is driven-by means of meshing tooth gears 74, 75 on thelower and upper roller shafts 64, 69 respectively.

The rollers 67, 68 as aforesaid are intended to feed the paper web orwebs forv the machine uses the paper in multiple thickness in its normaloperation, the feed being continuous and suflicient to supply a lengthof paper equal to the diameterof the blanks plus asurtable margin.preferably from a sixteenth to an eighth of an inch between the cuts foreach -Quarter turn of the dial, i..e., for each. step in the rotation ofthe dial as hereinafter described. The die pressing or bumping andpunching head 2 also includes means for imparting to the dial 3 which inthis instance has four pockets or apertures 275 equally spaced by arcsof 90 the step by step rotation aforesaid which places these pockets inturn in exact registration with the cutting die 18 and the crimping dieor stationary pressing die 44 and in alignment with the cutter l7 andthe bumping and punching members 41 and 43 which are as aforesaid inalignment with the cutting die 17 and stationary pressing die 44respectively. It should also he noted that for efficiency and facilityof operation the respective elements described are so arranged that. thetwo opposite holes or pockets 275 spaced by 180 are broughtsimultaneously in registration, one with the cutting die and cutter, theother with the pleating die and bumpcr and punch. To'this end the shaft27 of the reciprocating head 2 carries a bevel gear which meshes with abevel gear 81 on an upright shaft 82 mounted in suitable bearings 83 inthe frame, which shaft. 82 carries in its lower end ,an intermittent ormutilated gear 84 having a portion of the circumference 85 of a lengthcorresponding to one quarter of the circumference of the dial 3 toothedas shown,.the remainder of the circumference 86 being smooth. At the endof the toothed portion 85, a tooth 87 is provided of double width andthe dial 3, which has its circumference toothed at 88 to cooperate withthe intermittent gear, is provided at intervals amounting to one quarterof the circumference or with similar teeth 89 .of double width andcorresponding space 9.) adjacent the said teeth to receive the doublewidth teeth on the intermittent gean.

The double teeth are providedfor the purpose of taking up the initialstress incident to starting the dial after each dwell. The double tooth87 'is shown in contact with a double tooth 89 on the dial in Fig. 8. Inthis position the dial is about to start a quarter rotation. therotation of the dial being counter clockwise'as illustrated. The toothof the dial immediately adjacent cach space 90 in the form illustratedis cut away at 91 to provide for the meshing of the gears.

It will be apparent that when the dial comes to the end of each quarterrotation bringing the pockets or holes 75 into regis tration with thedies, that it has consider able moment of rotation. To arrest therotation of the dial and position it with the pockets in registrationwith the dies and alignment with the bumper and punch and cutter, thecross head'35 which carries the bumper is provided with a stop pin 95carried in a suitable socket 96 in the cross head. The stop pin 95 isset in a projectcorresponds to a pocket so that the pin 95 engages theblocks in turn stopping the dial in exactly the position to locate thepockets in turn in registration with the dies and in alignment with thebumper, the holes serve to lock the dial at each dwell preventingdisplacement. Further the pin 95 on account of its length continues inengagement with the dial sometime after the bumper cross head starts tomove upward when the punch has entered the die. The continued upwardtraverse of the bumper cross head releases the dial as the double tooth87 completes the rotation and comes in contact with the next doubletooth 89 on the dial. The meshing of the teeth on the dial with those ofthe intermittent gear accomplishes another quarter revolution moving thenext pocketinto registration with the dies, the parts being so timedthat the punch is completely or substantially withdrawn prior to themeshing of the tooth 87 so that it is moved from the path of thedialbefore the latter can come in contact with it.

Figs. 4, 5 and 6 illustrate the cutter timing mechanism by means ofwhich the cutter is timed in exact correspondence with the step by steprotation of the dial so that at each dwell of the dial the latter ispositioned with one of its pockets beneath the cutting die and eachcutting operation serves to deposit in a pocket of the dial, whichpocket is held in registration with the cutting dial, acut blank or anumber of cut blanks equal to the number of sheets composing the web.

To this end the pulley 6 which drives the shaft 7 which actuates thereciprocating cutter is mounted on the shaft to rotate relativelythereto and means is provided whereby the pulley is keyed t0 the shaftat intervals and released providing for the actuation of thereciprocating cutter at intervals corresponding to each dwell of thedial, during which the holes or pockets in the dial are positioned inalignment with the cutter and the cutting die. The face of the pulleyadjacent the shaftas shown in Fig. 5 and in dotted lines in Fig. 6 isprovided with four notches or indentations 100 adapted to be engaged bya key or bolt 101 carried by a collar 102 which is keyed to the shaft bymeans of a key 103 to ro- .tate therewith. The key 100 is mounted toslide in the collar in the direction of the axis of the shaft being tothis end seated in a groove 104.- in the collar and held by suitablecover plates 105 secured by any suitable means.

A spring 106 seated in an aperture 107 in the key and bearing againsttheend wall 108 of the groove 104 serves to impart to the key a tendency toslide to the left in the groove causing it to protrude from the collarand enter one of the notches or depressions 100. The key is also slottedtransversely as to its outer face at 208 and the collar hasa peripheralgroove 109 and the key has a follower or dog surface 110 at one side ofthe groove in the key which projects into the groove 109 in the collarwhen the key isadvanced, i.'e., projecting from the collar into one ofthe apertures or depressions in the pulley. Cooperating with thefollower or dog 110 is a cam 111 having a cam surface 112, the cam beingformed on the ley er 113 which is intermediately pivoted at 114 on asuitable stationary support and adapted to swing into and out of thegroove and into and out of the path of the dog or follower 110.

The shaft 7 has a right handed rotation as seen from the left in Fig. 5tending to bring the dog or follower 110 into contact with the camsurface 112 when the cam is in the groove. The action of the cam on thefollower throws the key to the right in Fig. 5 withdrawing it from thenotches or depressions in the face of the pulley and: releasing theshaft from the pulley so that the shaft tends to dwell with the followerin contact with the cam and with the cutter in withdrawn or upperposition. lVhen the cam is removed from the groove the key 101 isreleased, being projected by'the pressure of the spring 106 into a notchor depression 100 of the pulley 6 which is in continuous rotationlocking the pulley to the shaft, causing the shaft to rotate and actuatethe cutter. I

The cam lever 113 is in part controlled by a spiral spring 116 attachedat one end to the lever at the end opposite the cam 112 and to a fixedpoint 118 on the frame. The end 117 of the lever is alsopivotallyconnected to a rod 119 which is connected at its opposite endto theswinging end 120 of. a bell crank lever 121 pivotally mounted at 122 onthe frame and having a depending arm 123 engaged by a sliding rod 124 insuitable bearings 125, 126 in the frame, which rod is normallycontrolled by a spring 127 coiled about the rod and hearing at one end.against the bearing 126 and at the other end against the collar 128pinned on or otherwise secured to the rod. This rod '124 normallyprojects over and along lugs 130, four in number, that is, correspondingin number to the pockets 75 and so related to the pockets that each lug130 in turn comes in contact with the rod 124 thrusting it to the rightas seen in Fig. a, swinging the cam 111 out of the path of the followeror dog 110, releasing the key 101 permitting it to engage the pulley 6,wherey a single rotation is imparted to the shaft 7 resulting in asingle reciprocation of the cutter, causin it to operate once and cut asingle blank r set of blanks from the Web, it being understood that thelugs 130 are so related to the pockets or holes 75. and the cutter is sotimed as to operate during the dwell of one of the pockets 7 inregistration with the cutting die and in alignment with the cutter.

The rotation of the shaft 7 is arrested by the release of the key and bya brake to be described. The release of the key is accomplished at theend of each rotation of the shaft 7 by the cam 111 which is re turnedimmediately to the groove 109 by the action .of "the spring 16 when the,lug 130 passes out of contact with the end of the rod 124 which is atthe end of the dwell of the dial. The cam thus engages the followersurfaces 110 on the bolt 101 with.- drawing the bolt, releasing thepulley and. holding the bolt in Withdrawn position till the next lug 130comes into operation.

The brake is illustrated in Figs. 1 and being indicated by referencecharacter 135. It'consists of a circular band which is split and drawntogether by means of a screw 136 engaging the separate ends. The band isprovided with suitable brake lining 137 which bears against a drum 138on the shaft" and the band is further provided with a projecting arm139- which engages a fixed portion of the frame at 140 providing thedesired retardation which immediately stops the shaft when it isreleased from the pulley by the withdrawal of the key..

A suitable take-01f is provided which serves to remove the cut web fromthe machina and to prevent its accumulation in the vicinity of thecutter. This take-off may consist of a roller 141 driven by a belt 142from a pulley 143 ion the cutter shaft 7.

In operation the paper is fed by means of the rollers 67, 68, the feedpreferably beingcontinuous and at a rate which provides in excess of thedimensions of the blanks 'a sufficient margin, something lessv than aquarter of an inch to hold the waste together and in line so that it maybe conveniently drawn from the machine, the web being also for thispurpose slightly wider than the out. It is easily understood that theflexibility of the paper web will permit it to buckle and take up theportion fed when the cutter is down, the web being in. turn released andcaused to flatten and thrust its front edge forward when the cutter iswithdrawn.

The operation of the cutter 17 in connection with the cutting die 18 andthe timing time'of the cutting stroke, receives the cut blanks andcarries them to the bumping and crimping station where they are actedupon by the pressing die 44, the bumper or bumping die 41 and thepunching or drawing die 43.

In the form of the invention shown the pockets 75 are merely holes inthe rotating dial 3, the blanks being supported on and slid over theface of a stationary table or plate 150. With the pockets arranged at909 as shown and the bumping and cutting sta tions 180 apart there arenecessarily two stations, one at the front and one at the rear where nooperation takes place. The relative location of the pockets, the numberof pockets in the dial and the relative location of the cutting andpressing members, alsothe timing of the parts are widely variable andmay be regarded as matters of selection or design. s

As aforesaid the bumper precedes the punch, being set some 30 to aheadof it and also the bumper actuating mechanism is constructed with aconsiderable amount of play or 'back lash which is taken up by springs38 so that after the stroke of the bumper when the positive thrust ofthe mechanism is released, the bumping die is held against the paperpressing it against the stationary die by the action of the springsgiving a resilient or yielding rather than a positive grip so that thepunch which follows the bumper serves to draw the paper through andbetween the cooperating serrated surfaces 45 creasing or crimping the 4paper much more effectively than it can be done. by direct pressure- Theadjustments described in this connection compensate for any desiredthickness of web or variation in thickness.

-The cut waste is removed by any suitable take-off mechanism asaforesaid, indicated and described in connection with referencecharacters 140 to 145.

It is also noted that the feeding mechanism provides for adjustmentofthe rolls as to spacing andpressure so -that;web of any desiredtlnckness. can be used, meaning that any number of sheets which can: be

properly out and crimped may befed through the machine. Paper cups orwra pers which, constitute the product of t e machine indicated byreference character 160 are shown in the form of a single cup Fig. 10and a plurality of cups in Fig. 11,

the latter in the arrangement which they come from the machine.

Important advantages of the machine are convenience for arrangement, theperfection of the product, particularly as to efficiency of the crimpingoperation, universal adjustability and extra length of life andpossibility of cheap construction due to simplicity of design.
